METHOD FOR CAUSING HISTIDINE-SILVER COMPLEX TO EXHIBIT MICROBICIDAL ACTIVITY IN CHLORINE-ION-CONTAINING SOLUTION, LIQUID ADDITIVE COMPOSITION, AND LIQUID ANTIMICROBIAL COMPOSITION

摘要

PROBLEM TO BE SOLVED: To maintain the microbicidal activity of a histidine-silver complex even in a chlorine ion-containing liquid.

SOLUTION: There is provided a method for maintaining the microbicidal activity of the histidine-silver complex in a chlorine ion-containing liquid by adding a water-soluble nitrogen-containing polymer, namely either one of ε-polylysine and a mixture of a polyethyleneimine and ε-polylysine.
